Enter covering 12 the fan-shaped shape in section or hexagon shape and on etched plane axially disposed fluted 121 and/or protrusion
122；
Step 3: by the groove 121 on more input optical fibres 10 and carrying out mutually nested cooperation between protrusion 122, is formed and close beam
Optical fiber 20；
It is attached afterwards with the output optical fibre 30 for exposing optical fiber output covering 32 Step 4: fine 20 end faces of combined beam light are cut flat with,
Complete the production of high power signals bundling device.
The production method of the present embodiment only carries out laser ablation to optical fiber input covering 12, will not produce to input fibre core 13
Raw to destroy and have an impact to optical fiber input 12 internal structure of covering, bubble will not be generated in input optical fibre 10 by, which ensureing, asks
Topic；More input optical fibres 10 are carried out by mutually nested cooperation by mechanical clamp simultaneously, input optical fibre 10 is protected not and will receive and is crowded
It crushes bad.
Using production method described in the present embodiment, more input optical fibres 10 are passed through into rectangular or T shape groove 121 and protrusion
122 cooperations are nested together to form combined beam light fibre 20, without being subjected to fused biconical taper and sour technique, ensure input fibre core
13 will not deformation occurs, avoid introducing impurity, avoiding the occurrence of disconnected fine and mode excitation causes beam quality to deteriorate, while in optical fiber
Air bubble will not be generated in input covering 12, total reflection transmitting of the signal in input fibre core 13 is ensured, improves signal and close beam
The light ability to bear of device is conducive to transmitting high power signals；
In addition, not only solving air bubble problem by the high power signals bundling device that the production method of the present embodiment is completed, also existing
Discovery has better heat dissipation effect, which is because, when being 122 cooperation of groove 121 and protrusion in actual use, has very
Small gap, passes through for air molecule, and formation temperature is poor, forms certain air draught, takes away in combined beam light fibre 20
Heat.
The above is only a preferred embodiment of the invention, therefore all according to structure described in present patent application range
